A process for concentrating light by means of fluorescent compounds of the formula ##STR1## where the R.sup.1 's independently of one another are ortho-substituted aromatic or heterocyclic radicals which do not contain groups which confer solubility in water, and novel perylene-3,4,9,10-tetracarboxylic acid diimides of the formula I, where R.sup.1 is ##STR2## A.sup.1 and A.sup.2 being hydrogen, or one of A.sup.1 or A.sup.2 being isopropyl and the other being hydrogen. The compounds I are very lightfast and convert incident light into fluorescent light with high efficiency.
一种利用化学式为##STR1##的荧光化合物浓缩光线的方法,其中R.sup.1是独立的正位取代芳香或杂环基团,不含使其可溶于水的基团,以及新型的化学式为I的苝酞-3,4,9,10-四羧酸二酰亚胺,其中R.sup.1为##STR2##,A.sup.1和A.sup.2为氢,或者A.sup.1或A.sup.2为异丙基,另一个为氢。化合物I非常耐光且高效地将入射光转换为荧光光线。
